The turning tool is characterized in that the turning tool is also provided in the form of a plumbing fitting or as a component of a plumbing fitting, that he turning tool ( 5′ ) can be placed in a rotationally fixed manner on an outer or an inner periphery of the fitting ( 5 ) that is held on the water outlet armature, and or that he turning tool ( 5′ ) has a face profiling or contouring ( 24, 25 ) that can be placed in a rotationally fixed manner on a mating profiling or a mating contouring ( 25, 24 ) provided on the outlet face of the fitting ( 5 ) that is held in the water outlet armature ( 2 ).

BACKGROUND

The invention relates to a turning tool for turning a jet regulator, anozzle, an intermediate holder, a flow regulator, a non-return valve, ora similar plumbing fitting. This fitting, on the opening side, isdetachably held on a plumbing water outlet armature by means of a screwconnection or a bayonet connection, whereby the turning tool can beplaced on the plumbing fitting in a rotationally fixed manner.

Typically, a nozzle, in which a jet regulator is inserted, is screwedonto the opening-side outlet end of plumbing outlet armatures. This jetregulator should transform the water stream flowing into the regulatorinto a homogeneously aerated, soft water jet. Such jet regulators mustbe disassembled and exchanged at time intervals of several years. Forthis purpose, in order to screw the nozzle off of the outlet armatureand to be able to remove the jet regulator located in the nozzle fromthe nozzle, ring wrench-like turning tools have already been designed,which can be slid onto the nozzle from the opening side and can be setin a rotationally fixed manner in this position.

However, in an emergency this turning tool is usually not available forthe user. Above all, the production and purchase of this turning tool isassociated with an additional cost outlay.

SUMMARY

Therefore, the objective arises of creating a turning tool of the typenamed above, which helps to prevent the disadvantages of the known stateof the art described above.

In the turning tool of the type named above, the solution of thisobjective according to the invention is provided in that the turningtool is embodied as a plumbing fitting or as a component of a plumbingfitting and that the turning tool can be placed in a rotationally fixedmanner on the outer or inner periphery of the fitting held on the wateroutlet armature and/or that the turning tool has a face profiling orcontouring, which can be placed in a rotationally fixed manner on themating profiling or mating contouring provided on the outlet face of thefitting held on the water outlet armature.

According to the invention, the turning tool itself is formed as aplumbing fitting or at least as a component of such a plumbing fitting.Because the fitting used as the turning tool or the correspondingcomponent is required anyway by the manufacturer or user, the productionor creation of this turning tool is not associated with significantadditional costs. In order to be able to place the turning tool forturning on the fitting located on the water outlet armature in arotationally fixed manner, the fitting or the corresponding componentused as the turning tool can feature on its inlet or outlet face aprofiling or contouring, which can be placed in a rotationally fixedmanner on a mating profiling or mating contouring provided on the outletface of the fitting held on the water outlet armature. With the help ofthis turning tool, the screw connection or the bayonet or similar catchcan then be disengaged, which, up until then, had held the fitting onthe water outlet armature.

However, as an additional or alternative characteristic, the turningtool can also be placed in a rotationally fixed manner on the outer orinner periphery of the fitting held on the water outlet armature.

In this way, one simple and advantageous embodiment according to theinvention provides that the turning tool and the fitting held detachablyon the water outlet armature have outer contours adapted to each otherat least in sections such that these can be placed in each other in thisregion and can be connected to each other in a rotationally fixedmanner. Thus, the turning tool on one hand and the fitting located onthe water outlet armature on the other hand can have outer or innercontours adapted to the face regions that can be placed one on theother.

In this way, one embodiment according to the invention provides that thefitting held on the water outlet armature, at least in its opening-sideface region, has an outer outline or a clear inner opening, whichconforms in shape to the clear inner opening or to the outer outline ofthe turning tool, such that these parts can be inserted into each otherin this region in a rotationally fixed manner.

However, it is also possible that the turning tool or the fitting heldon the water outlet armature has on its inner periphery at least insections a contouring or profiling, which can be placed on a matingprofiling or mating contouring in a rotationally fixed manner when theother corresponding part is inserted in this position.

So that the turning tool can be placed particularly securely and tightlyon the outer or inner periphery of the fitting on the water outletarmature, it is advantageous if the turning tool is provided in theshape of a collar and formed as a nozzle, an intermediate holder, or ahousing of a plumbing fitting.

In certain applications, it can be necessary to exchange an aerated jetregulator with a non-aerated jet regulator or to replace a flow limiterwith a flow regulator. In such individual cases, the fitting or thecorresponding component used as a turning tool on one hand and thefitting on the water outlet armature on the other hand can be differentin shape and function. However, one preferred refinement according tothe invention provides that the turning tool is at least a component ofa fitting that is identical in function and/or shape to the fitting heldon the water outlet armature. Thus, for example, a collar-shapedhousing, which is identical in shape to the housing of the fittinglocated on the water outlet armature, can be used as the turning tool.Such a housing will be produced in large quantities, so that as aprecaution, a housing acting as a turning tool can also be added to eachfitting defined for the initial outfitting, without this beingassociated with special additional costs for the manufacturer or theuser.

One preferred embodiment according to the invention provides that theprofilings or contourings provided on the faces on the turning tool onone hand and on the fitting held on the water outlet armature on theother hand are formed in the shape of a crown.

In this way, in order to simplify the identically shaped construction ofthe fittings and their components, it is useful if the profilings orcontourings provided on the turning tool on one hand and the fittingheld detachably on the water outlet armature on the other hand areprovided on the outlet face of these parts.

The turning tool according to the invention can be used in largequantities especially where the turning tool on one hand and the fittingheld detachably on the water outlet armature on the other hand are eachconstructed as a jet regulator or at least as a component of a jetregulator.

Additional features of the invention emerge from the followingdescription of an embodiment according to the invention in connectionwith the claims, as well as the drawing. The present invention will beexplained in more detail with reference to the following embodiment.

BRIEF DESCRIPTION OF THE DRAWING

In the single FIGURE, a plumbing water outlet armature 2 is shown in theregion of its outlet end 4. A plumbing fitting 5, which here isconstructed as a jet regulator and which has a sieve attachment 14 onthe inflow side, is screwed into the water outlet armature 2 from theopening side. On the outer peripheral side, above an annular seal 11, anouter threading 1, which can be screwed into an internal threading 3 onthe inner periphery of the water outlet armature 2, is provided on thehousing of the fitting 5.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In order to be able to turn, when necessary, the fitting 5 that is helddetachably on the water outlet armature 2 and that can be screwedpractically completely into the water outlet armature 2 and in order tobe able to disengage this fitting from its screw connection in the wateroutlet armature 2, a turning tool is necessary, which is constructedaccording to the invention also as a plumbing fitting 5′ or at least asa component of a plumbing fitting.

In this way, the fitting 5′, which is used as the turning tool and whichalso is identical in function to that of the jet regulator, and thefitting 5 located in the water outlet armature 2 are identical in shape.

On the outlet faces of their housings, the fittings 5, 5′ have faceprofiling and mating profiling, respectively. These profilings andmating profilings are formed by the corresponding, crown-shaped face ofthe fitting housing, with the recesses 24 and projections 25 of one part5, 5′ provided on the crown-shaped face engaging in the projections 25and recesses 24 of the corresponding other part 5′, 5.

In the embodiment shown here, the fitting 5 located in the water outletarmature 2 can be unscrewed with the help of the fitting 5′ intended forreplacement and here identical in shape and function. The fitting 5′also acting as a jet regulator is then screwed into the water outletarmature with the help of the disassembled fitting 5. Thus, while here acomplete fitting 5′ is used for replacing the fitting 5 located in thewater outlet armature 2, it is nevertheless also possible to use onlythe housing of an otherwise not included fitting for unscrewing thefitting 5 located in the outlet armature. For this purpose, the fixturemanufacturer can supply only one additional housing with the fixture,with this housing being intended as the turning tool. This has theadvantage that the fixture manufacturer does not have to supply a secondfunctional unit, which can be mounted in the water outlet armature 2,and the other housing, which is intended as a turning tool and which isproduced and used in relatively large quantities, represents a veryeconomical aid.
